Question

Discuss Reliability Engineering for Cloud Systems.

Answer 1

Answer :

Reliability Engineering for Cloud Systems:

Cloud computing is the on-demand availability of computer system resources, like data storage, computing power, availability of hardware resources.

• All the resources are cloud based, so to use them synchronization or management of resources is very important.
• There reliability comes into picture.
• Reliability engineering for cloud systems is nothing but managing the resources for cloud computing in such a way that whenever computer asks for a resource, it should be available immediately without fail or with minimum waiting time.
• To make resources reliable , reliability engineering is the most important thing in which all the probable issues listed down.
• The backup plan is made to solve the all probable issues.
• To make the resource available to the computer whenever asked.
• To test the reliability of cloud computing systems specific constraints are used.
• To apply checks to improve reliability of Cloud applications deployed on real clouds similar issue is created and given it to the reliability engineer to see that how fast he can resolve that.
• Layered structure of Cloud system makes the reliability engineering more complex.
• Reliability is crucial part for maintaining customer confidence , users satisfaction and then by preventing revenue losses.
• Various algorithms are applied to maintain high availability of resources if one resources is failed we can provide another to the customer.
• Below is the process for reliability of resources:
• 

1. Failure analysis : Studying the possible issues in advance.
2. Design for reliability : Check for possible solutions
3. Reliability tests & data analysis : test the developed solutions to make system reliable.
